I'll try to reconstruct a part of the military history of Harold Roy Jennings, Sr..
As you know, the 9th Infantry Division fought in North Africa, Sicily, Normandy, Rhineland, Ardennes-Alsace and Central Europe.
Following the Sicily campaign, the division was routed to England, 25 Nov 43, to prepare for the invasion of France.
Which suggests that he was on English soil from that time until he landed in France.
The 9th Infantry Division crossed Utah Beach, 10 June 44 (D-Day +4); the 47th Infantry Regiment was committed to take high ground west of Orglades, 11 Jun 44; it took Octville, 26 Jun 44; the 47th IR and 60th IR took Cap de la Hague Peninsula, 29 Jun 44; the 9th ID crossed the River Marne in the Mieux area, 27 Aug 44; it continued the pursuit of the Germans east to the Namur-Dinant region; it crossed at Dinant against strong German resistance, and established a bridgehead, 6 Sep 44.
This will conclude his story, for he reportedly was Killed in Action, 5 Sep 44, probably at at or near the bridgehead at Dinant, France.
NOTE: You said that he died 9-11-19, which I take to have been his birth date.
That is all I can provide. I wish that it was more.
